Flow capacity

The heat recovery system typically handles flows up to about 12 liters/minute when showering - equivalent to the flow from a modern overhead shower.  

For flows greater than 12 liters/minute, the excess water will flow via the floor drain's overflow directly to the sewer (without heat recovery). The overflow ensures that the floor drain always functions as a normal floor drain with high flow capacity at worst.  

Normative flow capacity (for heat exchanger + board drain) is designed for flows > 80 liters/minute. Figures for normative flow capacity will be updated after independent type tests performed by RISE in the fall of 2023.

More from the knowledge bank

The design of the shower area and the location of the ventilation system play a major role in shower comfort, bathroom climate and, not least, energy efficiency.  
According to Boverket, the contribution of energy-saving technologies to improving energy performance may be included in the calculations based on the demonstrated energy savings of the technology.
Enduce does not reduce water consumption overall, but hot water consumption does. The resource saving lies mainly in the energy and not in the water.
